Romney's wife, Ann, took a turn as guest host on ABC's "Good Morning America" and spoke candidly about experiencing depression after she was diagnosed with multiple sclerosis 14 years ago. She said horses helped her recover her mental health.
"I was very, very weak and very much worried about my life, thinking I was going to be in a wheelchair as well. Turned to horses, my life has been dramatically different," she said. "They gave me the energy, the passion to get out of bed when I was so sick that I didn't think I'd ever want to get out of bed."
Mrs. Romney is part-owner of a horse that competed this summer in the Olympic sport of dressage, the equine equivalent of ballet.
